Patented Sept'. 1.5, 1935i @UNITED STATES PATE NT OFFICE vEBN'ES'I J.BISKAMP, 0F SAN ANTONIO, TEXAS msawasnm s This invention relates to dishwashing machines. One of its objects is to provide a portable structurewhich can be set up readily in a sink, on a drain board, or on asuitable stand 5 and, by connectin it to a hot water faucet, can beactuated e ciently without requiring the use of a motor or any mechanismof a complicated and expensive nature.

Another object is to provide an apparatus 0 of this character throughwhich there' is a constant iiow of fresh water which serves not only tothoroughly clean the contents of the washer but also to promptly removethe foreign substances.

parts of which are easily accessible or'the purpose of cleaning them ormaking repairs. v

A still further object is to provide a washer utilizing superposedrotatable spraying elements between which may be placed the articles tobe washed, the upper element or elements being removable with the coverof the washer thereby to permit convenient placing of the dishes, etc.in 'position to be washed. p Another object is to combine with themachine a simple and eiicient means for sup plying soap to the waterbeing directed onto ,the articles being washed.

With the foregoing and other objects in View which will appear as the'description proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the .invention herein disclosed may be made within thescope of what is claimed without departing from the spirit of theinvention. In the accompanying drawings the rpre- 'ferred forms of theinvention have been shown. In said drawings,

for holding dishes and other articles to be l cleaned.- If preferred,however, and as shown in Figure 12, the casing can be provided with foneor more ribs 5 pressed inwardly therefrom for supporting the racks.

In the structure illustrated there yis provided a lower rack and anupper rack. Both racks are formedof sti wire. The lower rack 6 includesa ring 7 across which are extended interwoven wires 8 widely spaced soas to offer the minimum obstruction to the ow ofwater. Certain of thewires have their middlev portions bent to` form upwardl extendinginclined yokes indicated at 9. hese okes, as shown particularlyin'Figur-e 1, are

dishes-in mclmed positions and spaced apart. The dishes have beenindicated by broken lines at D.

As illustrated in Figure 2, the upper rack 10 is formed of a wire ring11 having inwardly extended spaced parallel portions 12 which merge intoa central inner ring 13 concentric with the ring 11. The inwardlyextended portions 12 and the inner ring 13 are connected to the ring 11by crossed interwoven wires 14. Additional wires 15 which are likewiseinterwoven,`extend across and are connected to the ring 11 at pointswhere they are not intersected by ring 13 or the inwardly extendedportions 12. The rack constructed as described is left with a centralclearance 16 from which extends a radial clearance 17 opening throughthe margin of the rack.

Extending from the bottom portion of casing 1 is an outlet spout 18 andsecurely fastened to the outer side of the casing by any suitable meansis a distributing pipe 19 the lower portion 2O of which is extendedunder the bottom of the casing and opens into a spraying pipe 21 whichwill be hereinafter more fully described. The upper end of pipe 19 isconnected by a quick detachable coupling 22 of any desired constructionto a distribu ying pipe 23 which extends over and is suitably connectedto the cover 24 of casing 1. This cover is removably mounted on thecasing and can be lifted by means of a bail 25 or by means of knobs 26shown in Figure 13. I

Distributing pipe 23 opens into a pipe 27 which projects downwardlythrough the center of the cover 24. As shown particularly in Figure 9,this pipe 27 is engaged by a nut 28 which rests on the cover 24. Aspacingwasher or nut 29 extends around the pipe 27 and engages thebottoni surface of the cover. This spacing element is adapted to receivethrust from a hollow hub 30 rotatable on the pipe 27 and supported by acollar 31 which is detachably secured to the said pipe. The lower end ofthe pipe 27 is closed by any suitable means such as a screw plug 32 andcommunication is constantly maintained between the interior of the saidpipe and the interior of the hub through apertures 33.

A spraying pipe 34 extends radially from thehub 30 and opens thereinto.This pipe eX- tends close tothe wall of the casing 1 and is suppprtedclose to the cover 24. It has a series of apertures 35 extendinglongitudinally thereof, these apertures being inclined downwardly insuch a direction as to cause the pipe and hub to rotate when water orother liquid 1s discharged through the apertures.

Another pipe 36 is extended from the hub 30 downwardly through theclearance 16 and opens mto and supports a spraying pipe 37 arrangedunder but close to the rack 10. This spraying pipe is of'a length lessthan the combined lengths of the clearances 17 and 16 so that, when thepipe is positioned beneath said clearances, it can be withdrawnupwardpipe and the hub 30 -to rotate in the same direction as theseparts are propelled by water issuing from pipe 34.

The lower pipe 21 is constructed the same as pipe 27. 'lhe hollow hub 40which is rotatably mounted thereon has spraying pipes 41 and 42extending radially therefrom. Both of these pipes have upwardly inclinedapertures 43 arranged in longitudinal series for directing jets of waterupwardly toward raclr4 6 and at the same time rotating the pipes and thehub 40 in a direction opposite to that in which the upper hub and itspipes rotate.

F or the purpose of limiting the rotation of the hub 30 and the pipescarried thereby, a yieldingly supported plunger 44 is slidably mountedin the cover 24 and is normally held out of the path of pipe 34. Thisplunger has a head or button 45 by means of which it can be depressedreadily to bring the plunger into the path of pipe 34. Thus the pipewill be brought to a stop by the plunger at a point where the pipe 37will be positioned under the clearances 16 and 17. Consequently, byuncoupling distributing pipe 23 from distributing pipe 19, the cover canbe raised and pipe 37 can move upwardly through the clearances withoutdisturbing the rack 10 or any of the articles supported thereby.

The distributing pipe 19 has a nipple 46 opening thereinto. This isadapted to be detachably engaged by a soap container 47. The outlet endof the container may be provided with a screen 48 for preventingparticles of soap from flowing into the machine. A hose 49 is connectedto the other end of the container and constitutes a means for directinghot water from a faucet or other outlet to the machine. The soapcontainer 47 can be connected to the nipple 46 by means of a stud 5()adapted to be received by a bayonet slot 51 as shown in Figure 1 or itcan be screwed onto the nipple as shown at 52-in Figure 10. A small cakeof soap indicated at S is adapted to be held loosely in the container 47so that the water flowing through the container will slowly dissolve thesoap and carry it to the spraying pipes.

If desired, liquid soap can be supplied to the machine. For this purposea soap container 53 can be supported upon and open into a container 54similar to container 47 Soap container 53 has a normally closed inlet 55at the top thereof and a by-pass 56 extends from container 54 to the topof container 53.
